Main
Text
On
April 1, 2010 the ISO will implement Scarcity Pricing and Ancillary Service
Procurement in the Hour-Ahead Scheduling Process. On April 15, the ISO
will implement Forbidden Operating Regions. It is imperative that
affected market participants are prepared to operate successfully under the
market rules introduced by these initiatives.
The
ISO seeks feedback from market participants who need additional support in
preparing for the launch of these market enhancements. The purpose of the
three initiatives and impacted participants are outlined below.
Scarcity Pricing - April 1 go-live
- Purpose: Provides a
mechanism for ancillary service prices to automatically rise to
pre-defined levels when reserves are scarce, providing enhanced price
signals to the market.
·
Impacted
market participants:
This initiative will particularly affect scheduling coordinators that
participate in the ancillary service markets.
Ancillary Service Procurement in the
Hour-Ahead Scheduling Process - April 1 go-live
- Purpose: Incorporates into
the ISO market systems the procurement of ancillary services in the
hour-ahead scheduling process as well as the dispatch of those reserves in
real time.
·
Impacted
market participants: This initiative will impact scheduling coordinators that
have hourly pre-dispatch resources that are certified to provide ancillary
services.
Forbidden Operating Regions - April 15 go-live
- Purpose: Incorporates
changes to ISO systems to honor forbidden operating regions, which are
distinct non-overlapping operating regions within which generating
resources cannot operate stably, in the real-time market for resources
with certain characteristics.
·
Impacted
market participants: This initiative will impact scheduling coordinators that
have generation resources with defined forbidden operating regions registered
in the Master File.
Market participants that are comfortable with their preparedness
do not need to respond to this market notice.
Participants
that need assistance in preparing for the launch of these initiatives should
immediately contact Janet Morris at jmorris@caiso.com
or at (916) 608-7337.
